- HR Polyurethane foam base (38 kg/m3), with 8 cm. of height. Its height porosity allows a great air circulation through the foam.
- Intermediate layer made of HR polyurethane foam with more density (42 kg/m3), with 4 cm. of height that provide more comfort and stability.
- Thermosensitive viscoelastic foam (50 kg/m3), with 4 cm. height for the upper layer. In contact with the body, the viscolastic foam turns softer, keeping the same supporting level and endowing an excellent comfort levels
